Title: Innovations by Richard M Cheng

Introduction

Richard M Cheng is a notable inventor based in Montreal, Canada. He has made significant contributions to the field of polymer materials and bioprinting technologies. With a total of five patents to his name, Cheng's work focuses on advancing the capabilities of fluidic systems and bioprinting instruments.

Latest Patents

Cheng's latest patents include innovative systems, devices, and methods for inducing anisotropy in polymeric materials. These systems utilize a fluidic device to distribute a polymer solution and a flow-confining solution, generating a layered flow. This layered flow is designed to create a polymer liquid sheet that is sheathed by flow-confining liquid sheets. The fluidic device consists of first and second fluid conduits, where the second conduit has a reduced height, leading to hydrodynamic focusing. This process reduces the thickness of the polymer liquid sheet and induces molecular alignment and anisotropy as the sheet hardens.

Another significant patent involves devices and methods for wound-conformal guidance of a bioprinter printhead. This instrument allows for the in situ formation of architected planar biomaterials and tissues. It translates a printer head along a deposition surface, such as a patient with burn injuries. The handheld instrument perfuses cell-laden biopolymer solutions through a moving microfabricated printer head, depositing them onto a stationary surface or wound. A soft deformable roller is incorporated to minimize further damage to the injured area, ensuring that the printer head does not exert undue pressure on the wound.
